Summary: The subtropical Atlantic coastal zone of southeastern Florida supports nearly 7 million inhabitants on a coastal plain conurbation that stretches from West Palm Beach to Miami. About a quarter of the present population originally settled on higher topography along the shore-parallel Atlantic Coastal Ridge. From about the middle 1900s, however, urbanization intensified along the shore and spread westward into freshwater marshlands. Population densities approaching 2500 persons per km-2 along some coastal sectors and dredge and fill operations to create urban land in western marshes degraded coastal environments bringing in question sustainability. Efforts to maintain environmental integrity initially focused on shore protection first via hard engineering works, which later on included massive beach renourishment projects along developed coasts subject to critical erosion. Marine algal blooms, led to eutrophication, degraded coastal water quality, and deterioration of coral reefs indicate environmental problems at least as serious as beach erosion. Recognition of a potential eco-catastrophe, collapse of entire marine and coastal wetland ecosystems in southern Florida, led turn to the Everglades Restoration Project, the largest single environmental recovery effort in the world. Cleanup of terrestrial systems is essential to sustainability of marine ecosystems now jeopardized by nutrient loading.
